(third-person singular simple present loops, present participle looping, simple past and past participle looped)
From Middle English loupe (“noose, loop”), earlier lowp-knot (“loop-knot”), of North Germanic origin, ultimately from Old Norse hlaup (“a run", literally, "a leap”), used in the sense of a "running knot". Compare Swedish löp-knut (“loop-knot”), Danish løb-knude (“a running knot”), Danish løb (“a course”). More at leap.
loop - Computer Definition
- An electrical loop, i.e. closed electrical circuit. The two conductors of an electrical loop compose one wire carrying the go signal and the other carrying the electrical return signal.The circuit is closed and the loop is completed when the conductors are connected.
- A local loop. In the broader contemporary sense, any access circuit between the customer premises and the edge of the telco network, or that of any other service provider, is termed a local loop, whether it is electrically-based or employs optical or radio energy. See also local loop.
- A physical configuration used in residential or small business inside wire installations. Such a configuration connects multiple voice telephone jacks to one or two pairs of wires in a continuous, shared electrical loop. See also home run.
In programming, a repetition within a program. Whenever a process must be repeated, a loop is set up to handle it. A program has a main loop and a series of minor loops, which are nested within the main loop. Learning how to set up loops is what programming technique is all about. The following example prints an invoice. The main loop reads the order record and prints the invoice until there are no more orders to read. After printing date and name and addresses, the program prints a variable number of line items. The code that prints the line items is contained in a loop and repeated as many times as required.
